is that chromatin is (biology) a complex of dna, rna and proteins within the cell nucleus out of which chromosomes condense during cell division while nucleoplasm is the protoplasm of a cell nucleus.
What is the difference between nucleus and nucleoplasm?
Nucleoplasm is the living part of the nucleus that is surrounded by a nuclear membrane.
Distinguish between Cytoplasm and nucleoplasm.
|It is made up of water and structural filaments and cell organelles.||It is composed of nucleolus and chromatin material.|
|It is surrounded by a cell membrane.||It is surrounded by a nuclear membrane.|
What is in the nucleoplasm?
The nucleoplasm has a complex chemical composition, it is composed mainly of the nuclear proteins but it also contains other inorganic and organic substances such as nucleic acids, proteins, enzymes and minerals. … The nucleoplasm contains many enzymes which are necessary for the synthesis of the DNA and RNA.
What is the difference between protoplasm and nucleoplasm?
Each cell consists of a living part that is called the protoplasm and is found to be enclosed by a plasma membrane.
State the difference between Cytoplasm and protoplasm.
|It is made up of water and structural filaments.||It is made up of cytoplasm, nucleoplasm, and nucleus.|
Is DNA in nucleoplasm?
The nucleoplasm is the central area in the cell that contains the genetic material. … Proteins that play a role in DNA compaction, DNA replication, and transcription are most likely at the periphery of the nucleoplasm, because they are excluded from the DNA-rich region (see below).
Is chromatin in the nucleoplasm?
The nucleus stores chromatin (DNA plus proteins) in a gel-like substance called the nucleoplasm. The nucleolus is a condensed region of chromatin where ribosome synthesis occurs. The boundary of the nucleus is called the nuclear envelope.
What is the difference between chromatin and chromosome?
The DNA is packaged by special proteins called histones to form chromatin. The chromatin further condenses to form chromosomes. This means chromatin is lower order of DNA organization whereas chromosomes are higher order of DNA organization.
What do you mean by chromatin?
Chromatin is a complex of DNA and proteins that forms chromosomes within the nucleus of eukaryotic cells. … Each nucleosome is composed of DNA wrapped around eight proteins called histones.
What is chromatin material?
Chromatin is the material that makes up a chromosome that consists of DNA and protein. The major proteins in chromatin are proteins called histones. They act as packaging elements for the DNA. … And that arrangement is called chromatin.
What is called nucleoplasm?
The nucleoplasm is a type of protoplasm that makes up the cell nucleus, the most prominent organelle of the eukaryotic cell. It is enclosed by the nuclear envelope, also known as the nuclear membrane. … Nucleoplasm is also known as karyoplasm, karyolymph or nucleus sap.
Is nucleoplasm and cytoplasm same?
The cytoplasm is found in all the cells while nucleoplasm is found only in eukaryotic cells. The cytoplasm is the fluid mass of the cell consisting of organelles whereas nucleoplasm is the sap of the nucleus that contains nucleoplasm.
What is difference between RER and SER?
Smooth ER is derived from rough endoplasmic reticulum by sacrificing the ribosomes, whereas Rough ER originates from the nuclear membrane. The main difference between the SER and RER is the presence of ribosomes, as SER does not consist of ribosomes but RER consists of ribosomes.
What is the function of nucleoplasm?
The most prominent nucleoplasm function is to serve as a suspending substance for the organelles within a nucleus. Additionally, it aids in maintaining the structure and shape of a nucleus. Furthermore, it plays a vital role in transporting materials necessary for cell metabolism and functioning.
Where is chromatin found?
Chromatin is a complex of macromolecules composed of DNA, RNA, and protein, which is found inside the nucleus of eukaryotic cells.
What is the difference between nucleolus and chromatin?
Chromatin is the name for the diffuse granular mass of DNA found in interphase cells. … Euchromatin is “active” chromatin, containing DNA sequences that are being transcribed into RNA. The nucleolus is the site in the nucleus where ribosomal RNA is transcribed.
What is lysosome function?
A lysosome is a membrane-bound cell organelle that contains digestive enzymes. … They break down excess or worn-out cell parts. They may be used to destroy invading viruses and bacteria. If the cell is damaged beyond repair, lysosomes can help it to self-destruct in a process called programmed cell death, or apoptosis.
